ELECTRIC ALARM AND CALL-BELL.

SPECIFICATION arming part of Letters Patent No. 588,997,1iated August 31, 1897.

i I Application tiled January 11, 1897- Serial lilo. 618,806. (No model.) l

TovaZZ whom it may concern:

Be it vknown that I, FRANK C. J CRDAN, a citizen of the United States, residing at VVadsworth, in the county of 'Medina and State of Ohio, Vhave invented a certain new and useful vImprovement in' Electric Alarms and Call- Bells, of which the following is a specification. My invention has relation to improvements in electric alarms and call-bells, and it is an improvement andV elaboration of the device for which I was granted Letters Patent of the United States No. 560,096 on May 12, 1896.

The objects of my invention are to provide improved devices whereby the connection of the contact-finger with the hour-hand may be utilized to ring a desired series of different bells at determinate places simultaneously, to provide means by which the bell in any selected room may be readily arranged as a burglar-alarm for all parts of the house, and to still further provide that an alarm may be simultaneously given by all bells at a determinate time, and, finally, givinga general alarm on all bells in cases of emergency without'disturbing the previously-arranged parts.

To the' aforesaid objects my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically point'- ed out inthe claiins,reference being had to the accompanying. drawings, which constitute a part of this specification.

In the accompanying drawings, in which similar reference letters and numerals indicate like parts in the different views, Figure.

1 is a front elevation of a clock provided with my invention; Fig. 2, a vertical section of the same at the line :c of Fig. 1; Fig. 3, a back elevation, enlarged, of the switchboard for connecting different bells with the contactnger or other signaling apparatus; Fig. 4, a

l section of the same at the line y y of Fig. 3;

Fig. 5, a side elevation of the clock-case to show the relation of certain binding-posts and wires to other parts; Fig. 6, an inverted plan of the switchboard for giving a general alarm; Fig. 7, a section of the same at the line Z Z of Fig. 6, and Fig. 8 a diagrammatic view of theline'connections. Y Y f n Referring to the'dra'win gs, 1 isth'e clock-case containing-the clock-train 2, the hour-hand shaft 3 of which is connected by a wire 4 with one pole 5 of'a battery 6. About the clockdial is a sheet-metal rim 7, which preferably extends beyond the plane of the clock-dial and is adapted to receive contact-fingers 8, each of which consists of a block of insulating material having on the bottom jaws to grasp the rim 7 and a projecting strip of metal adapted to lie in the path of and lightly touch and make electrical connection with the hourhand as it passes, and each finger has its metalA stri p connected by a,wire cord 9 with a contact-plate of a switchboard 10, hereinafter described. VThus far the apparatus is substantially the same as that described in my former patent, hereinbefore referred to;

lThe switchboard, which for compactness and convenience is attached to the front of the clock-case, consists of a non-conducting board 10, faced for convenience of attaching it to the case by a metallic plate 11, and is provided with series of plug-holes, the number of which will depend upon l[he requirements of the clock.

In the illustrations there are three series of plug-holes 12 13 14 15 16, 2O 21 22 23 24, 30 31 32 33 34 35 in Figs. 1 and 2 and four series 12 13 1415 16, 2O 21 22 23 24, 30 31 32 33 34 351,40y f4l 42 43 44 in Figs. 3 and 4, the upper series 12 13 14 15 16 in each having no electrical connection, but simply serve as a rack for plugs 25 26 27 2S 29 when they are not in use, and these plugs have no other connection. ltwill be noticed in Fig. 3 that series 30 31 32 33 34 35 are placed intermediately between series 2O 21 22 23 24 for a purpose to be stated. On the back of the board 10 between the series of holes 2O 21 22 23 24 are fastened a series of plates 51 52 53 54 55, the ends of each plate except the end half-plates being curved outward to lie in the path, but without touching each other, of a plug when inserted in the hole and thus be electrically connected by the plug. In the center of each plate 50 51 52 53 54 55 is also fastened a short transverse plate 83 S9 90 91 92 93, withits free end ing the holes as just stated, and below this series another set of plates 45 46 47 48 49, bearing the same relative position to the holes 40 41 42 43 44 and for a similar purpose, and each IOC) plate 45 40 47 48 49 is connected with its adjacent plate 88 80 00 01 02 08 by a wire 17.

The multiplying-board 5G, which for convenience and coinpactness I prefer to place under the clock as a shelf, consists of a board 56, of non-conducting material, on which at selected distances are attached strips 58 50 (50 (51 02 (i3 G4 (35 GC 67 ot' sheet metal, fastened at one end and with their free ends slightly bent outward, and to this board are connected two sliding bars 68 (50, having beveled edges to slide under and engage the strips 58 to 07, inclusive, these bars being` united by metallic cross-pieces 70, provided with slots 71, through which pass screws to retain them. This frame of bars 68 6!) and cross-pieces 70 is provided with a handle 105, by which it may be moved forward to bring the bars G8 69 sim ultaneously into contact with their respective sets of strips 58 to 67, inclusive, and returned to break the contact.

The wire connections are as follows: The hour-hand shaft 3 is connected with one pole, 5, ot the battery G by a wire 4, and by a second wire 19 with the central binding-post 18 at the side of the clock. From the opposite pole, 118, of the battery ti a wire 72 runs to the right binding-post 78, from which a wire 74, by means ot branch wires 75 7G 77 78, connects severally with one binding-post of each ofthe bells A B C AD. From the opposite posts of these bells wires 70, 80, 81, and 82 run separately to one of the plates 58, 50, G0, and G1 of the multiplying-board 5G, and from the same plates separa-te electric cords 83 84 85 8G run to plugs 56 37 38 80 through holes in the board 10 of less diameter than the plug-handles, so that when not in use the plugs will stand on the board 10, as shown in Figs. 1 and 2, and the slack of these cords is taken. up by pulley-weights 87 below the board.

To each plate 50 51 52 53 54 55, Fig. 8, is attached a wire cord and a contact-fin ger Similar to the one shown for plate 50, but as they are all the same the one shown is believed to be sullieient.

Now supposing` that it is desired to ring bell A at three oclock, bell B at four oelock, bell C at five oclock, and bell D at six oclock, I proceed first to remove the plugs from the holes 20 22 23 24. Then I place the contactfinger of plate 51, Fig. 8, at three oclocl; on the clock-face, the contact-iin ger for plate 52 at four oclock, the contact-linger for plate 53 at five oclock, and the contact-finger for plate 54 at six oclock. Now when the hour-hand reaches three oclock the circuit will be closed through bell A as follows: From pole 5 of battery ti through the following: wire 4, hourhand 3, contact-fin ger at three oclock to plate 51, plate 80, plug 36, wire 83, plate 58, wire 79, bell A, wire 75, wire 74, post 73, wire 72 to battery. This will ring bell A only and at the hour decided on, and when the hour-hand reaches four oelock the circuit will be closed through bell B as follows: from battery-post 5, wire 4, hour-hand shaft 3, contact and cord on plate 52, plate 90, plug 37, cord 84, plate 5S), wire 80, bell B, wire 70, wire 74, post 73, wire 72 to battery. This will ring bell l only at four oclock, and at tive oclock the same thing will be repeated for bell C and at six ocloclc for bell D, and this is the only way separate bells can be rung separately. In order to ring bells A and I3 at, say, three oclock, place the contact-finger for either plate 51 or plate 52 at three ocloclc on the clock-face and insert a plug in hole 21 and the current will pass through both bells simultaneously7 and this may be carried to any extent by plugging into holes 20 21 22 23 24.

The entire upper series may be connected by unconnected plugs 25 26 27 28 29 in the holes 20 21 22 24 and connected plugs 3G 37 38 3U 111 1l2in the holes 30 31 34 35, or selected bells from the upper series may be rung by connecting the intermediate plates 50 51 58 54 55 50 by unconnected plugs 25 20 27 28 29 and placing connected plugs 3G 37 38 30 in the holes adjacent to the corresponding plates 88 89 90 91 92 03, or selected bells from series 30 31 32 33 34 35 and 40 41 42 43 44 may be simultaneously rung from one contact-linger by connecting plates 50 51 52 53 54 55 by plugs 25 20 27 28 2f) to the desired bells and placing connected plugs 30 37 38 3f) in the holes adjacent to the plates corresponding to the selected bells, the upper connection between the series 30 S1 32 S4 35 and 40 41 42 43 44 of the contact-plates being secured by the wire 17, hereinbefore referred to.

By combining all plates in the series 50 51 52 54 55 and placing connecting-plugs in the holes 30 3182 33 34 55 and 40 41 42 43 44, Fig. 3, all bells may be rung simultaneously by the clock at a deinite previously-arranged time. To accomplish this latter object and to avoid the necessity of placing all plugs in position-a matter of some labor when there is a great number of roomsthe device shown in Figs. 0 and 7 is employed. The wire connections of the plates 58 5f) 00 01 of this board are, as already explained, each connected by a wire 70 8O 81 82 with one binding-post of one of the bells A B C D.

The sliding frame, composed of bars 68, G0, and 70, is connected by a wire 100 with the binding-post 101 on the clock-case, which in turn is connected by a wire 102 with the plate 88 and this latter,y as hereinbefore stated, with the contact-linger 8.

By sliding the plates U8 G9 into contact with the plates 58 59 (50 61 all the bells will be in the circuit and all will ring when the hourhand touches the contact-linger 8.

Vthen it is desired to simultaneously ring all the bells at a time not previously arranged, as in cases of emergency7 when a general alarm is necessary, the same device shown in Figs. G and 7 is used. The binding-posts 18 and 101 are connected by a wire 103, broken between its ends and arranged to be closed by a push-button 104. I'Ience when it is desired to give a general alarm the plates G8 (30 IOO IIO

the circuit if the window is raised or the door opened. l

When the window is opened, the current will pass' from the pole 5 through wire 4 to the shaft 3, thence through line 19, post 18, and line 106 to the circuit-closer at the window 108, and return through line 107, post 101, line 102, plate 88, plug in hole 20, plate 5l, plate 89, plug 36, line 83, plate 58, line 79 to the bell A, and thence by line 75, post 73, line 72, to pole 113 of the battery.

Having described the operation of burglaralarm with bell A, let us select bell D and show that that bell may be utilized as aburglar-alarm, so that the occupant of that room may be notified by the closing of the circuit -at the window. It may be done in two ways,

first byinserting plug 39 in hole 30, and then thecircuit would be as follows: one side of circuit-breaker at the window through wire 107, post 101, wire 102, plate 50, plate 88, plug 39, line 86, plate 60, wire 82, bell D, Wire 78, wire 74, post 73, wire 72, battery 6, wire 4, wire 19, post 18, wire 108 to window-,circuit breaker. Or it may be done as follows: Insert plug 39 in hole 34 remove the plugs 38 37 36 from holesv33 3231 and insert plugs 25 26 27 28 in holes 20 22 23 24, and then the circuit would be from window by wire- 107, post 101, wire 102, plate 50, plug 25, plate 51, plug 26, plate 52, plug 27 plate 53, plug 28 to plate 54 to plate 92, wire 86 and back to Window, as j ust described in the former method.

To ring all bells on closing the circuit at the Window, insert plugs 36 37 38 39 in holes 31 32 33 34 and all bells will ring in the same Y manner as was just described for bell D.
